Acute normovolemic hemodilution (ANH) has long been employed for reducing allogenic blood transfusion for cardiac surgery, and hydroxyethyl starch has been used as an intravenous replacement fluid during ANH procedure. However, possible impact of ANH employing HES on blood viscosity and oxygen delivery have not been well investigated in patients undergoing off-pump coronary artery bypass (OPCAB) surgery . Anesthesia is induced and maintained by using propofol-remifentanil-rocuronium in OPCAB surgery (n=21). ANH is performed by using 5 ml/kg of blood salvage and administering 5 ml/kg of balanced HES 130/0.42 (Tetraspan™) for 15 min during vascular graft harvesting. For the present study, three arterial blood samples (3 ml each) are taken before (Sample 1) and after ANH (sample 2 and 3) and they are stored in 3 tubes. Sample 3 (in tube) undergoes further 30% in-vitro dilution by adding 1-1.5 ml HES. By using a scanning capillary tube viscometer (Hemovister™), Blood viscosity at low shear rate (5/sec) of the three samples are determined. By using a formula with blood viscosity and hematocrit, tissue O2 delivery index (TODI, = hematocrit/viscosity at 5/sec) is calculated.
To determine the relationships of a variety of nutrients, foods, and dietary patterns with the subsequent risk of developing type 2 diabetes, cardiovascular disease, and mortality in US men and women.
The Mindfulness Intervention as Myocardial Infarction Rehabilitation Additive (MIMIRA) study aimed at studying the feasibility and acceptability of Mindfulness Based Stress Reduction - an 8 week course in meditation and yoga - in patients with a recent coronary artery event and elevated depressive symptoms. To address these questions patients with elevated scores on a depression scale were invited to participate in MBSR, and there evaluation of the course as well as a panel of psychological risk factors and resources was measured.
the purpose of this study is to determine whether appropriate control of diabetes around the PCI time is related with MACE and outcome of diabetic patients.
Vascular calcification is a frequent complication in dialysis patients and is strongly associated with mortality. Its pathogenesis is complex and involves a series of markers that act on the vascular microenvironment. There is evidence that aldosterone is one of the biomarkers and may have a role in osteoinductive pathways.The aim of this study was to evaluate the effect of spironolactone, an inhibitor of mineralocorticoid receptor, in the progression of coronary calcification in patients undergoing peritoneal dialysis.
ST elevation myocardial infarction (STEMI) patients affected by multivessels coronary artery stenosis, represent a clinical relevant problem. The management and prognosis of these patents are supported by few literature data. Therefore, in this study authors enrolled real world diabetic vs. non diabetic patients admitted for STEMI and associated to multi vessels coronary disease. Then these diabetics were divided in incretin users (6 months of incretin treatment before study enrollment) vs. never incretin users. In these patients authors studied all cause mortality, cardiac mortality, and major adverse cardiac events at 12 months follow up.
This study will retrospectively review and compare clinical outcomes between left atrial appendage occlusion with dual antiplatelet therapy versus conventional antithrombotic therapy in patients with atrial fibrillation undergoing drug-eluting stent implantation.
The purpose of this study is to determine if the routine use of a sheathless 7F guide catheter for transradial percutaneous coronary intervention (TR PCI) is non-inferior to a 6F sheath/guide combination with regards to radial artery injury (radial artery intimal-medial-adventitial thickening). To evaluate the radial artery, ultrahigh resolution ultrasonography (55 mHz) will be used to accurately quantify radial artery intimal-medial-adventitial thickness (IMT) at baseline and 90 days. A non-inferiority analysis will be performed to compare the degree of radial artery IMT at 90 days between the 7F sheathless guide approach and the 6F sheath/guide combination.
Elective percutaneous coronary intervention (PCI) is often associated with myocardial necrosis evidenced by peri-procedural troponin release. This is a surrogate for subsequent cardiovascular events. There is no study on the effect of peri-PCI oxygenation in in myocardial protection and cardiopulmonary fitness outcome. Patients with higher baseline cardiopulmonary fitness will have lower mortality. This study is to assess the utility of oxygen to reduce ischaemia in patients with significant stable coronary artery disease scheduled for elective PCI. The secondary objective is to evaluate further effect of peri- PCI oxygenation on cardiovascular fitness and autonomic response.
Cardiovascular diseases (CVD) are responsible, throughout the world, for high mortality rates and cardiovascular morbidity. Endothelial dysfunction is the earliest marker of clinical atherosclerosis development. Human studies show that endothelial and microvascular dysfunction are independent predictors of ischemic cardiovascular events and long-term prognosis. The study´s objective is to evaluate the endothelial and peripheral microcirculation changes by venous occlusion plethysmography (VOP), nailfoldvideocapillaroscopy (NVC) and serum biomarkers in patients with myocardial ischemia detected by scintigraphy and normal coronarography.
